T0 ALL WHM IT MAY CONCERN:

Be it known that we, SETE W. HERBIGK and CuAnLEs G. GILBERT, Jr., of Salem, in the county of Salem, and State of New Jersey, have invented a new and improved Machine lfor Preparing Burlaps and other Fabrics in the Manufacture nf Floor, Carriage, Table, and other Oil-Cloth; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference bcinghad to the accompanying drawings, making a part of this specication, in which- I Figure 1 is a side elevation, arid I Figure 2 a. plane view ofthe said machine- Like letters of reference indicating the same parts when in the different figures.

In the manufacture of door oil-cloth, Ste., the foundation fabric, after being sized with glue, has heretofore been stretehedin a. frame, to remove wrinkles preparatory to and whilst coating it with the foundation paint. The object of our invention is to produce a machine whereby a permanently even and at surface can be more readily given-to the burlap or 'other fabric 'used in the manufacture ofiloor, carriage, table, and other oil-cloth; and our said 'invention consists in the peculiar arrangement and combination of rollers and heated pressingcyl'inders'operating together, substantially as'hercinafter described and set forth.

In the drawings, A B are the supporting-franne of the machine; C C the pressing-cylinders, and D D1 D2 Da the rollers. The rollers D andthe lower cylinder C rotate freely on their journal-bearings in the same horizontal plane on the upper side rails a1 b of the frame A B, and are arranged parallel to and at about equal distances from each other, as seen in iig. 2. The cylinder C is suspended by its journals in a swinging frame, E, so as to be directly above and parallel to the lower cylinder C', and so that it can when weighted, as hereinafter described, bc readily raised from and lowered into contactuwith the latter by the foot of the attendant pressed down Vupon a treadle, F, which is hung from n lever, G, that is coupled to the'swinging frame E, and

has its fulerum in o. bearing xed on a. raised portion, a2, of the said frame. Both of the cylinders C C aremade of east iron or other metal, and are constructed so as to admit of being heated by steam or otherwise. Upon each of the two projecting arms e1 e2 of the sningingframeE a heavy block of cast iron, G', is adjustably secured, for 'the purpose of giving a proper degree of pressing power to the cylinder C. On onejournalof the roller DI a grooved friction-pulley, H, is fixed, and over the pulley ametalstrap, L, fits and passes down into connection with the treadle h2, whereby the attendant can readily increase the friction of the said roller D, and on one of the journals of the rollerD a crank-handle is attached, whereby another attendant can give it rotary motion.

Operation.

The fabric whichY is to be prepared or made even and dat. after it has been sized, is first wound tightly around upon the roller Dl by using a crank-liandlo to be applied on its journal d. l'.lhev free end of the cloth is then carried from its under side over the roller D. then betweenthe two cylinders C C', and over the roller D2 to the under side of the roller D, where it is fastened by an overlap, 4as indicated by the faint lne'sg/y in g. 1. The cylinders having been made sulliciently hot, one of the attendants now winds the fabric slowly upon -the rollerD from theroller D", causing it to pass between the hot rotating cylinders ,C C under the pressure of the upper cylinder C and the weights G G of'the swinging frame E, thus meshing down all the lumps and removing the wrinkles and other inequalities ofthe fabric, and therefore making it permanently even and flat. And should a -n'ave be formed in the cloth in .front of or just before the cylinders, the attendantk who has control of the unwinding roller D and the cylinder C places his foot upon the treadle h2, and thus increasing the friction of the latter while the winding roller D is kept in motion by its attendant, and the weighted cylinder being at the same time slightly raised by means of ,the treadle F or lever-G the wave in the cloth is readily removed, and immediately after the'said result has been produced the weighted cylinder C and roller D are allowed to return to thei" former conditions.

This is avery simply-operating machine for thev purpose, and electually prepares the cloth for the immediate operations of painting and printing without requiring the use of a stretching-frame, as heretofore.

Having thus fully described our improved machine. what we claim as our .invention therein, and desire to secure by Letters Patent, is confined to the following, viz:

We claim the described arrangement of the rollersD and D, the cylinders C and C', the friction-pulleyH, with its strap tnnd treadle it", and the weighted swinging frame E, the said parts being combined together in a. suitable frame, A B, sons to operate substantially' as and for the purpose described.
